The xsk_socket__create() function fails and returns an error if it cannot get the XDP_OPTIONS through getsockopt(). However, support for XDP_OPTIONS was not added until kernel 5.3, so this means that creating XSK sockets always fails on older kernels. Since the option is just used to set the zero-copy flag in the xsk struct, and that flag is not really used for anything yet, just remove the getsockopt() call until a proper use for it is introduced.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
